THEODOR KUNDTZ, 0F LAKEWOOD, OHIO.

BLOWER, EXHAUSTER, AND THE LIKE.

To all whom it may concern:

Be it known that I, THEODOR KUNDTZ, a citizen of the United States ofAmerica, re-

siding at Lakewood, in the county of Guyahoga and State of Ohio,

have invented certain new and useful Improvements in Blowers,Exhausters, and the Like; and I hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in blowers, exhausters and thelike for mills and factories.

The primary object of this invention is to operatively mount thesuitably housed fan-Wheel of a blower, exhauster or the like upon anend-portion of a line-shaft employed in a room of a mill or factorybuilding and thereby produce a very powerful and economically operatedblower, exhauster or the like.

Another object of this invention is to have the said end-portion of theline-shaft outer side of an outer wall of the said room and tooperatively provide the said projecting portion of the line-shaft withthe fanwheel of a blower, exhauster or the like,

or housing which is supported externally of the said wall andindependently of the lineshaft so that the said blower, exhauster or thelike is arranged wholly externally of the i said wall and therefore outof the way.

40 a wall of the chamber formed by and within Another object is toprovide a seat adjacent the said wall for the said housing so that thelatter is adequately supported. Another object is to form the inner endthe housing by a vertically arranged plate arranged adjacent the saidwall, and to have the remainder of the housing formed by a bonnet whichis removably secured to the said plate so that the said bonnet can beremoved outwardly and endwise from the projecting portion of theline-shaft to afford access to the fan-wheel on the shaft and to theinterior of the housing.

Another object is to avoid the necessity of using a separate engine ormotor or belting or gearing or other separate powertransmitting means inthe operation of the fan-wheel thus arranged adjacent the said wall, toavoid costly frame-work for sup- Specificetion of Letters Patent.

porting the housing, to prevent any bearing of any portion of thehousing upon the lineshaft, to avoid the necessity of using bearings onor in the housing, to avoid lubrication of any portion of the housingand fanwheel.

Another object is to provide a blower, exhauster, or the like, whichrequires substantially no care or attention, and which is simple anddurable in construction, readily installed at the aforesaid end-portionof the line-shaft, inexpensively maintained, economically operated,reliable and eflicient in its operation and not liable to get out oforder.

-With these objects in view, and to the end of realizing any otheradvantages hereinafter appearing, this invention consists in certainfeatures of construction, and combinations and arrangements of parts,hereinafter described, pointed out in the claims, and illustrated in theaccompanying drawings.

In the said drawings,Figure1 isatop plan of a blower, exhauster, or thelike, embodying my invention, and shows in section, an outer wallexternally of and from which the housing of the said blower, exhausteror the like is supported. Fig. 2 is a central vertical section on line2-2, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 isa vertical section on line 3--8, Fig. 2, looking inwardly. Fig. 4 is avertical section on line 4- Fig. 2, looking outwardly.

Referring to the said drawings, A indicates an outer side wall of a roomR in a mill or factory building, and B indicates a line-shaft employedwithin the said room. The line-shaft B is arranged substantiallyhorizontally and supported in any approved manner. The line-shaft B hasone of its end-portions extending loosely through a correspondinglyarranged hole a formed in and extending laterally through the wall A,and the said end-portion of the line-shaft projects, as at b, a suitabledistance beyond the outer side of the said wall. Preferably the Wall Ais provided at its inner side with a box C which affords bearing to thelineshaft.

D indicates the fan-wheel of my improved blower, exhauster, or the like.The said fanwheel is operatively mounted on the projecting end-portion bof the line-shaft at the outer side of the wall A. A casing or housingincloses the fan-wheel D and comprises a metal plate G and a metal hoodor bonnet g.

The plate or housing-section G is arranged substantially vertically atthe outer side of the wall A and rests upon a seat formed by a shelf 8which is formed externally of the said wall by a lateral and outwardenlargement of the wall under the housing. The plate or housing-sectionG is preferably suitably secured in any approved manner to the wall A,and forms the inner end wall of the chamber 15 formed by and within thehousing and containing the fan-wheel D. The plate or housing-section Gis of course provided centrally with a hole to accommodate the locationand operation of the line-shaft.

The metal bonnet 9 forms opposite side walls, the top wall and the outerend wall of the chamber 15 and is placed in position over the fan-wheelfrom the outer end of the projecting end-portion b of the lineshaft. Thebonnet b is provided at its inner end and externally with an outwardlyprojecting flange 13 which extends over the top and sides of the bonnetand overlaps the outer side of the plate or housing-section G which istherefore large enough in dimensions to overlap the inner side of theflange 13 and project, as at 14, somewhat beyond the said flange.

The plate or housing-section G is provided at its lower end with alaterally and outwardly projecting flange 16 which rests upon the seatformed by the shelf 8, and the bonnet g rests upon the said flange andconsequently is supported from the said shelf or seat.

The bonnet g is secured at its flange 13 preferably removably by bolts17 and nuts 18 to the plate or housing-section g. The bolts 17 havetheir heads countersunk in the inner side of the plate orhousing-section G and have their shanks projecting through the flange13, and the nuts 18 are mounted on the said shanks at the outer side ofthe said flange. The bonnet g is provided at its lower end andexternally with. laterally and outwardly projecting flanges 20 and 20which are arranged at opposite sides respectively of the saidhousing-section and project laterally and outwardly over and rest uponthe flange 16 of the plate or housing-section Gr.

By the construction hereinbefore described it will be observed that thehousing is supported from the wall A independently of the line-shaftB,-that is, independently of any box which affords bearing to theline-shaft,and the bonnet g, upon removing the nuts 18 to detach thebonnet from i the plate or housing-section G is rendered free to beremoved from over the flange 16 of the last-mentioned housing-sectionand consequently from the supporting shelf 8 to afford access to thefan-wheel and interior of the housing.

The chamber 15 is provided cent-rally of its outer end-wall andconsequently centrally of the bonnet g, wit-h an inlet formed by a flueh which is suitably attached to the bonnet and is arranged centrally andexternally of the bonnet g and opposite or adjacent the outer or freeextremity of the end-portion of the line-shaft, which flue discharges atits inner end through an opening 21 formed in the bonnet 9 into theaforesaid chamber and is employed in conducting the dust or material tobe conveyed to the said chamber from any desired place, which materialduring the operation of the fan-wheel is sucked or drawn into the. saidchamber through the said flue.

The bonnet g has its upper portion provided at one side with an upwardlyprojecting tubular member 24: which communicates with and forms theoutlet of the fancontaining chamber, through which outlet any dust orother matter sucked into the said chamber during the rotation of thefanwheel is discharged from the chamber, and L represents a flue or pipefor conducting the discharge from the said outlet to any desired place.

By the construction hereinbefore described it will be observed that theobjects of my invent-ion as hereinbefore stated are economically andconveniently attained.

What I claim is 1. The combination, with a wall of a room in a building,and a suitably supported shaft arranged substantially horizontally andhaving an end-portion which extends through the said wall and projectsexternally of the said room, of a fan-wheel operatively mounted on thesaid projecting portion of the shaft, and a casing or housing inclosingthe fanwheel and comprising a suitably supported upright metal platearranged adjacent the said wall and forming the inner end wall of thefan-wheel-containing chamber formed in and by the housing, said housingalso comprising a suitably nally of the said room, of a fan-wheeloperatively mounted on the said projecting portion of the shaft, and acasing or housing inclosing the fan-wheel and comprising a suitablysupported upright plate arranged adjacent the said wall and forming theinner end wall of the fan-containing-chamber formed in and by thehousing, said housing also comprising a suitably supported bonnetforming the top wall, side Wall and outer end Wall of the said chamberand removably secured to the aforesaid plate, said chamber having aninlet and an outlet.

3. The combination, with a wall of a room in a building, a seat arrangedat one side of the wall, and a suitably supported shaft arrangedsubstantially horizontally and extending over the seat, of a fan-wheelarranged over the seat and operatively mounted on the shaft, and acasing or housing inclosing the fan-Wheel and comprising an uprightplate arranged adjacent the said wall and forming one of the end wallsof the fan wheel containing chamber formed in and by the housing, whichplate is provided at its lower end and externally with a laterally andoutwardly projecting flange resting upon the aforesaid seat, saidhousing also comprising a bonnet which forms the top wall, side wallsand opposite end Wall of the said chamber and rests upon the saidflange, said chamber having an inlet and an outlet.

In testimony whereof, I sign the foregoing specification, in thepresence of two witnesses.
